HARRY 0. SMITH, OF LOS ANGELES, CALIFORNIA.

FASTENER.

Original application filed February 16, 1921, Serial No. 445,376. Divided and this application filed 31, 1921. Serial No. 473,680.

To all whom it may concern:

Be it known that I, HARRY 0. Saturn, a citizen of the United States, residing at Los Angeles, in the county of .Los Angeles and State of California, have invented certain new and useful Improvements in Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 1

This invention relates to improvements in fasteners, being a division of my application filed February 16th, 1921 and serially numbered 145,376 and has for its primary object the provision of means for anchoring the spring in the female member so as to permit the ends of the spring to be exposed for gripping the male member and thereby retain the latter connected to the female member against accidental detachment.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a vertical sectional view illustrating a fastener constructed in accordance with my invention,

Figure 2 is a perspective view illustrating the female member,

Figure 3 is a horizontal sectional view illustrating the means of securing the spring within the female member,

Figure 4 is a plan view illustrating one form of spring,

Figure 5 is a similar view illustrating another form of spring.

Figure 6 is a plan view illustrating two members held against separation by my invention.

Referring in detail to the drawings, the numeral 1 indicates a male member while the numeral 2 indicates a female member. The male and female members each include a base 3 having formed integrally therewith a tubular member 4 of hollow formation adapted to be passed through the artiole to which the device is applied and then Specification of Letters Patent.

May

headed as clearly shown in Figure 1. The bases are of elongated formation and the base of the male member has formed upon one end a shank 5 terminating into a ball or sphere 6 adapted to be received by the female member 2. The female member 2 has formed upon its base a dome-shaped portion 7 provided with an opening 8 in its front wall and a slot 9 in its bottom wall. The opening 8 and the slot 9 have communication with each other as shown in Figure 2 so that the male member or the ball 6 and shank thereof may be moved into and out of the female member. The slot 9 of the female member forms a flange 10 adapted to form a seat for a substantially U-shaped spring'll. The ends of the spring 11 are curved outwardly and rearwardly to form tension portions 12 adapted to bear against the wall of the dome-shaped portion 7 when said spring is seated upon the flange 10. The flange 10 has formed thereon a flange 13 adapted to overlie a part of the spring 11 and is of a. curvature to correspond with the curvature of the spring, and has its ends spaced from the opening 8 so as to expose the end portions of the spring and permit them to overlie the slot 9 and to engage and grip the male member or its shank 5 when inserted in the slot 9.

In Figure 5 a slight modification of spring is shown in which the ends 14 are curved outwardly, rearwardly and inwardly over the U-shaped portion.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination, and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim is 1. A fastener including male and female members, a dome-shaped portion formed on the female member and having an opening in its front wall and a slot in its bottom wall to receive the male member, a flange formed in the dome-shaped portion, a spring resting on said flange, a second flange formed on the first named flange and bent to overlie said spring and of substantially U-shape having its ends spaced away from the opening of the dome-shaped portion to expose the ends of the spring.

A fastener including male and female members, a dome-shaped portion formed on the female member and having an'opening wall to receive the male member, a flange formed in the dome-shaped portion, a substantially U-shaped spring resting on said flange, a second flange formed on the first named flange and bent to overlie said spring and of substantially U-shape, having its ends spaced from the opening of the dome-shaped portion to expose the end portions of the spr1ng. v

In testimony whereof I aflix my signature in presence of two Witnesses.
